To all whom it may concern.

Be' it known that I, GU's'rAvn Honrnn, a citizen of. the United, States,residing at Seattle, in' the county of King andState of Wash ington,have invented ajcertain new and use ful Improvement in Valves, of whichthe following is a'specificatiofn.

My invention relates tonew. and useful improvements in valves that areparticularly, adapted for controlling, the flow of liquids through pipeswherein hydraulic prftessurfe is maintained, and the principal objects"of my ii'ivention'areto providefavalve that lS adapted to be normallyheld in a closed.'.po-" ion brhvd au iepress ar and which y be manuallyopened by turning a valve handle.

Further objects are to provide a valve having a pressure chamber with aconduit connection wherein an inner tube extends upwardly into a cupmember of the valve and whereby fluid pressure is forcibly and directlybrought into engagement with said valve to hold the same against itsseat.

Still further objects are to provide a valve that is simple and durablein construction, reliable and efficientin operation and which isentirely free of all springs, gaskets or packings.

With the above and'other objects in view which shall appear as thedescription proceeds, my invention consists of novel construction,adaptation, arrangement and combination of parts hereinafter describedby devices illustrated in the accompanying drawings, wherein Figure 1 isa view in central vertical section of a faucet showing the valve in theopen position;

Fig. 2 is a view partly in elevation and partly in vertical showing thevalve in a closed position;

Fig. 3 is a view in horizontal section taken on a broken line 3, 3 ofFig. 1; and

Fig. 4.- is a detail view in elevation of the valve proper.

Referring to the drawings throughout which like reference numeralsdesignate like parts, the numeral 5 indicates the base portion of afaucet that is provided with a depending reduced threaded portion 6adapted to be secured to a conduit or supply pipe. An inner pipe 7 isthreadedly secured within said reduced portion and projects upwardlyinto a pressure chamber 8 provided within said base portion. A wirescreen 9 is interp se Wi -1 i sa d nn r pipe a d n sm n .03 s p ov d dth r i i r s in s idtssr sure chamber as willbe readily understood.

P ide w a l nin 'l4 fissd ys9are th siand beveled: a i lower O en-e d t form ja alve s etw valve-l is lidablymau ted withinthe chamber 13. The upper portion of said-valve comprisesa plurality of verticalribs pecedrela i nwitha ee trali pl ne l8 and istherefore adapted for the free passagbf fluids. Y

The lower portion of the valve is made in the shape of an inverted cup19 adapted to fit over the upper end portion of the pipe 7 withsuflicient space between for the free passage of liquid. The conicalsection, as designated by the numeral 20, between the upper and lowerportions of said valve is arranged to engage the seat 15 as'will bereadily understood. It will now be apparent that the hydraulic pressurewithin the chamber 8 will hold the valve in a normally closed positionas clearly shownin Fig. 20f the drawings. The pressure is broughtdirectly and forcibly upwardly within the cup 19.

The means for manually operating the valve comprises a valve stem 21provided at its upper end with a handle 22 and at its lower end with aworm portion 23 threadedly mounted within vthe casing 11 and whose lowerextremity is adapted to functionally engage the top of the valve 16.

The upper end of the casing 11 is reduced and'threaded to receive a cap24. A recess 25 is provided within said upper end and is internallythreaded to receive a nipple 26 that fits snugly around the stem 21.Said nipple is provided with diametrically disposed slots 27 adapted toreceive a key or other instrument for the purpose of turning the nippleand thus adjusting the movement of said valve stem.

The stem 21 is provided with a reduced portion and two half rings 28 arearranged to fit therein and to ride up and down with said stem. Saidhalf rings will abut against the floor of the recess 25 at the limit oftheir downward movement and at the limit of their upward movement theywill engage the nipple 26. It will be obvious that the throw of saidstem may be regulated by turning said nipple.

Referring to Fig. 2 of the drawings, as hereinbefore stated, the actionof the fiuid within the chamber 8 and pipe 7 in pressing upwardlyagainst the cup'19 will hold the valve in a normally closed position. Byturning the handle 22 in a counter clockwise direction the lowerextremity of thestem 21 will push the valve downwardly to the openposition shown in Fig. 1 and the fluid will pass freely through saidvalve and will continue to discharge through the nozzle 12 as long assaid handle is held in this position.

By turning the handle 22 in the reverse direction to raise said stem thepressure of the liquid will again cause said valve to immediately followsaid stem upwardly as will be readily apparent. The peculiar design ofthe upper portion of said valve will serve to disseminate the force ofthe water in its discharge.

What I claim is:

; 1. A valve slidably mounted within a cas-.

ing, the upper portion of said valve comprising a plurality of ribs inspaced relation, a cup member for the lower portion of said valve, aninner tube projecting within said member and said valve adapted to beheld in a normally closed position by hydraulic pressure acting throughsaid tube against said cup member.

2. A valve slidably mounted within a casing, a valve seat within saidcasing, a pressure chamber within said casing, drainage means for saidpressure chamber, a tube projecting into said pressure chamber, aplurality of ribs disposed in spaced relation upon the upper portionofsaid valve, and a conical portion disposed upon the lower portion ofsaid valve and adapted to be held in nor mal engagement with said valveseat when a pressure is exerted against the bottom portion of saidvalve.

In witness whereof, I hereunto subscribe my name this 11th day ofFebruary A. D. 1925.
